Description

Technical Field

[0001] The invention relates to the technical field of concrete block production, in particular to an automatic steel wire cutting device for concrete blocks. Background Art

[0002] Large concrete blocks usually refer to large-sized precast concrete components used in construction and civil engineering. These blocks have a large volume and weight and are often used in structures such as walls, foundations, and retaining walls. When making large concrete blocks, it is necessary to add steel wires with a diameter of 4.0mm-6.0mm layer by layer to the inside of the concrete during the pouring process to improve the strength and durability of the large concrete blocks. In the process of adding steel wires to the poured concrete, the steel wires must first be automatically cut to the corresponding size to reduce manual operation time and ensure that the steel wires can be quickly and accurately cut to the required size, thereby speeding up the entire concrete pouring process.

[0003] At present, there are the following disadvantages in cutting steel wires: 1. When cutting steel wires automatically, it is usually necessary to gather multiple steel wires together first, and then send them into the corresponding cutting device to cut the multiple steel wires at one time. During the above cutting process, if the front ends of the multiple steel wires are not completely parallel or closely arranged, the cutting results will be uneven, and the cutting lengths of some steel wires may be inconsistent, affecting subsequent use. In addition, cutting multiple steel wires at one time will increase the burden on the tool, thereby causing the cutting tool to wear faster, affecting the cutting quality and efficiency, and increasing the cost of maintenance and replacement of the tool; 2. After the cutting is completed, workers are required to collect and remove the cut steel wires before the next automatic cutting can be carried out. Manual collection and removal takes time, which leads to stagnation of the production line, reduces overall production efficiency, and affects the smoothness of the continuous operation of steel wire cutting. In addition, manual operation will lead to some human errors, such as missing or wrong collection, or failure to clean the cutting equipment in time, which affects the subsequent cutting quality.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The transmission part 43 includes a second rotating ring 431, a second motor 432, an L-shaped support plate 433, a spline shaft 434 and a spline sleeve 435. The rear end surface of the support cylinder 3 is equipped with a second rotating ring 431 through a bearing, and a second motor 432 is fixedly installed on the support cylinder 3. The output end of the second motor 432 is connected to the second rotating ring 431 through a second gear set. The rear end surface of the second rotating ring 431 is fixedly installed with a second bevel gear ring. The rear end surface of the support cylinder 3 is rotatably equipped with a spline sleeve 435 corresponding to the support plate 411 through a bearing seat. The spline sleeve 435 is fixedly sleeved with a second bevel gear, and the second bevel gear ring is meshed with a plurality of second bevel gears at the same time. The rear end surface of the first slider 413 is fixedly equipped with an L-shaped support plate 433, and a spline shaft 434 spline-matched with the corresponding spline sleeve 435 is installed on the horizontal section of the L-shaped support plate 433 through a bearing.

[0039] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The transport part 44 includes a first rotating shaft 441, a rubber roller 442, a second rotating shaft 443 and a third rotating shaft 444. A side wall of the feeding plate 414 away from the corresponding support plate 411 is rotatably installed with two first rotating shafts 441 located at the rear side of the cutting groove 415 and distributed front and back through a bearing seat. A rubber roller 442 is fixedly sleeved on the first rotating shaft 441. A second rotating shaft 443 is installed through a bearing in the feeding plate 414. The front first rotating shaft 441 is connected to the corresponding second rotating shaft 443 through a belt transmission. A third rotating shaft 444 that passes through the vertical section of the corresponding L-shaped support plate 433 is installed in the feeding plate 414 through a bearing. The third rotating shaft 444 and the second rotating shaft 443 are connected through a first transmission bevel gear set. The third rotating shaft 444 and the corresponding spline shaft 434 are connected through a second transmission bevel gear set.

[0040] During the specific work, when it is necessary to cut multiple steel wires, the worker first passes the steel wire to be cut through the rear rubber roller 442 and the feed plate 414 until the steel wire passes through the front rubber roller 442 and the feed plate 414, and moves the front ends of all steel wires to the cutting groove 415 to ensure that the front ends of all steel wires are in a flush state when the transport part 44 transports the steel wires. Then the above operation can be repeated to install other steel wires on other feed plates 414, thereby completing the loading operation of multiple steel wires.

[0041] Then, the second motor 432 is started to rotate the second rotating ring 431 through the second gear group, and the second rotating ring 431 will drive several spline sleeves 435 to rotate synchronously through the cooperation of the second bevel gear and the second bevel gear ring. Taking the uppermost feeding plate 414 as an example, the spline sleeve 435 will rotate the spline shaft 434, and the spline shaft 434 will rotate the third rotating shaft 444 through the second transmission bevel gear group, and the third rotating shaft 444 will rotate the second rotating shaft 443 through the first transmission bevel gear group, so that the second rotating shaft 443 rotates with the first rotating shaft 441 at the front end under the cooperation of the belt, so that the front end of the steel wire is transported forward a certain distance through the front rubber roller 442, so that the multiple steel wires are synchronously moved to the position corresponding to the cutting part 51, and when the front end of the steel wire moves forward to the required length, the second motor 432 is stopped. At this time, the position of the steel wire to be cut corresponds to the cutting groove 415.

[0042] When the transport part 44 cooperates with the transmission part 43 to transport the steel wire, the rubber rollers 442 on the front and rear sides will simultaneously squeeze the direction in which the steel wire enters, thereby pressing the steel wire against the side wall of the feeding plate 414 close to each other, thereby ensuring that the steel wire remains in a horizontal state and is transported forward.

[0043] When the transportation is completed, the first motor 422 is started to rotate the first rotating ring 421 through the first gear group, and the screw barrel 423 on the support plates 411 is synchronously rotated through the first bevel gear ring and the first bevel gear. The feeding plate 414 is restricted by the first slider 413, so that the screw barrel 423 cooperates with the screw rod 424, driving the surrounding feeding plates 414 to synchronously approach the cutting part 51.

[0044] See also Figure 1 and Figure 3 The cutting part 51 includes a stand 511, a third motor 512 and a circular saw 513. The upper end surface of the support seat 2 is fixedly installed with a stand 511 located in front of the support tube 3 and symmetrical in the front and back. The circular saw 513 is rotatably installed between the front and back symmetrical stands 511. The third motor 512 is fixedly installed on one of the stands 511. The output end of the third motor 512 is fixedly connected to the circular saw 513, and the circular saw 513 is coaxial with the support tube 3.

[0045] See also Figure 1 , Figure 3 , Figure 4 and Figure 7The guide portion 52 includes a fixed rod 521, a guide cross plate 522, a guide rod 523 and a slide plate 524. The front and rear symmetrical seats 511 are fixedly installed with fixed rods 521 corresponding to the support plates 411 one by one. The end of the fixed rod 521 away from the corresponding seat 511 is fixedly installed with a guide cross plate 522. The side wall of the feeding plate 414 close to the corresponding support plate 411 is fixedly installed with a slide plate 524. The side wall of the guide cross plate 522 close to the corresponding support plate 411 is fixedly installed with a guide rod 523 symmetrical to the corresponding fixed rod 521. The two groups of symmetrical guide rods 523 facing each other slide together and penetrate the corresponding slide plate 524.

[0046] See also Figure 1 , Figure 3 and Figure 7 The clamping portion 53 includes a second slideway 531, a clamping slider 532, a bidirectional screw 533 and a rack 534. A side wall of the feeding plate 414 away from the corresponding support plate 411 is provided with a second slideway 531 located in front of the corresponding cutting groove 415. A bidirectional screw 533 is installed through the second slideway 531 through a bearing. A clamping slider 532 that is symmetrical on both sides and threadedly connected to the corresponding bidirectional screw 533 is slidably installed in the second slideway 531. A first transmission gear is fixedly sleeved on the bidirectional screw 533. A rack 534 meshingly connected to the first transmission gear is fixedly installed between the support plate 411 and the stand 511.

[0047] During specific operation, before the surrounding feeding plates 414 synchronously approach the cutting part 51, the third motor 512 is started to rotate with the circular saw 513, and the front and rear stands 511 can maintain the stability of the circular saw 513 during cutting. In the process of the feeding plate 414 approaching the circular saw 513, the first transmission gear will cooperate with the rack 534 to rotate the bidirectional screw 533, so that the clamping sliders 532 on both sides synchronously approach the steel wire, and when the feeding plate 414 is about to reach the position of the circular saw 513, the clamping sliders 532 on both sides will fix the front end of the steel wire.

[0048] When the feeding plate 414 approaches the circular saw 513, two sets of symmetrical guide rods 523 facing each other will slide on the slide plate 524 to provide guidance for the feeding plate 414 and keep the feeding plate 414 stable when feeding. Then, the first motor 422 is started to make the feeding plates 414 around the circular saw 513 synchronously approach the circular saw 513. At this time, the cutting groove 415 corresponds to the circular saw 513. When the feeding plate 414 moves until the circular saw 513 is located in the cutting groove 415, the cutting of multiple steel wires is completed, thereby reducing the cutting time and operation cycle, and significantly improving production efficiency.

[0049] After the cutting is completed, the first motor 422 is started in reverse to make the feeding plate 414 synchronously move away from the circular saw 513 until it returns to its original position, and then the second motor 432 is started to transport the plurality of steel wires forward.

[0050] See also Figure 1 , Figure 7 and Figure 8 The mating part 61 includes a mating groove 611, a mating plate 612, a spring 613 and a clamping rod 614. A mating groove 611 is provided at the front end of the feeding plate 414. The mating plate 612 is hinged in the mating groove 611 through an arranged shaft rod. A spring 613 is fixedly installed between the upper end of the mating plate 612 and the corresponding feeding plate 414. The lower end of the mating plate 612 is hinged with a left-right symmetrical clamping rod 614 through an arranged torsion spring. The clamping rod 614 is covered with a rubber layer.

[0051] See also Figure 1 , Figure 7 and Figure 8 The expansion portion 62 includes a fixed column 621 and a trapezoidal block 622. The fixed column 621 is fixedly installed at the front end of the matching groove 611. The fixed column 621 is fixedly installed with a trapezoidal block 622 whose area increases from back to front. The trapezoidal block 622 is located between the corresponding left-right symmetrical clamping rods 614.

[0052] During specific operation, before cutting, the feeding plate 414 is in a position close to the support plate 411. At this time, the upper end of the matching plate 612 presses against the lower end surface of the support plate 411 and compresses the spring 613. At this time, the matching plate 612 will rotate with the axis rod as the hinge point, so that the left-right symmetrical clamping rod 614 at the lower end presses against the left and right sides of the trapezoidal block 622 and is in an open state, so that when the feeding mechanism 4 transports the steel wire forward, the clamping rod 614 will not press against the front of the steel wire to block its movement.

[0053] As the feeding plate 414 approaches the circular saw 513, the upper end of the matching plate 612 gradually stops pressing against the lower end surface of the support plate 411, and rotates forward under the action of the spring 613. At this time, the left-right symmetrical clamping rods 614 gradually separate from the left and right sides of the trapezoidal block 622. The left-right symmetrical clamping rods 614 approach the front end of the steel wire under the action of the torsion spring and clamp the front end of the steel wire.

[0054] After the cutting is completed, when the feed plate 414 moves away from the circular saw 513, the upper end of the matching plate 612 will be pressed against the lower end surface of the support plate 411 again. At this time, the left-right symmetrical clamping rod 614 is in a state of not contacting the trapezoidal block 622. When the upper end of the matching plate 612 rotates backward, the cut steel wire will be clamped by the left-right symmetrical clamping rod 614 and pushed forward a certain distance. When the left-right symmetrical clamping rod 614 contacts the trapezoidal block 622, the cut steel wire will be released. In this way, the cut steel wire can be adaptively pushed forward for feeding, so as to automatically feed the cut steel wire, reduce the time of manual feeding, and greatly improve the overall production efficiency. After the feed plate 414 returns to its original position, the clamping rod 614 is reset.

[0055] See also Figure 1 — Figure 8 Working principle: When multiple steel wires need to be cut, the worker first passes the steel wire to be cut through the front rubber roller 442 and the feeding plate 414, and then repeats the above operation to install other steel wires on other feeding plates 414, thereby completing the feeding operation of multiple steel wires.

[0056] Then, the second motor 432 is started, and the multiple steel wires are synchronously moved to the position corresponding to the cutting part 51 through the cooperation of the transport part 44 and the transmission part 43. When the front end of the steel wire moves forward to the required length, the second motor 432 is stopped, and then the first motor 422 is started, and the surrounding feeding plates 414 are driven by the driving part 42 to synchronously approach the cutting part 51.

[0057] Then the third motor 512 is started to rotate the circular saw 513, and the clamping part 53 will fix the front end of the steel wire. Then the first motor 422 is started again, so that the surrounding feeding plates 414 are synchronously close to the circular saw 513. At this time, the cutting groove 415 corresponds to the circular saw 513. When the feeding plate 414 moves until the circular saw 513 is located in the cutting groove 415, the simultaneous cutting of multiple steel wires is completed.
